The composition begins in cut-time with open chords underlying a simple flute melody. The marimba moves briefly to a running eighth-note accompaniment before taking over the melody sustained as repeated eighth notes. Utilizing a gradual ritardando and metric modulation, the piece shifts into 12/8 time with the marimba providing a solid eighth-note bassline for a more energetic and aggressive flute melody. This up-tempo portion is briefly interrupted by a 4/4 section that is more lyrical and restrained. Following an accelerando and another metric modulation, the duet shifts to a reprise of the energetic 12/8 idea which concludes the piece.
